A plane mirror is a flat surface that is high-reflection coated. A plane mirror always produces a virtual image of ideal, i.e., diffraction-limited quality. The image is left-right reversed Fig. 2.2 (a). When the mirror is rotated by an angle θ, the reflected ray is rotated by 2θ. If two plane mirrors enclose an angle θ, then 360°/θ° − 1 images are formed of an object placed inside the mirrors. The mirror is used for path folding, path switching, in optical levers for measurement, in kaleidoscopes, etc. Semitransparent mirrors are used as beam splitters. The reflectivity of a mirror can be enhanced by depositing a dielectric coating on top of a metallic coating. Such enhanced reflectivity mirrors are also commercially available.

Concave mirrors (or converging mirrors) are curved mirrors where the reflective surface depresses inward and away from the light source. Unlike convex mirrors, concave mirrors are used to reflect light inward and thus are capable of focusing incoming light rays (Figure 2.11). Depending on the object distance from the concave reflecting surface, different image types are formed with varying orientation, magnification, and entity (real or virtual).

The ISWP WSPBKT was purposefully developed to be agnostic to context (i.e. relevant across cultures) and to mirror fundamental, basic principles that are described in the WHO Guidelines. The ISWP WSPBKT was piloted and preliminarily validated by subject-matter experts (Burrola-Mendez, Goldberg et al., 2018). The open-source test on ISWP’s Wheelchair International Network (WIN) website mirrors the WHO ‘8 steps’ process for providing wheelchairs, and 75 multiple-choice questions are drawn randomly across 7 domains (assessment, fitting, follow-up, prescription, process, production, user training) resulting in a unique exam for each test taker. Since the initial pilot phase and as of September 2020, the test has been translated from English to 14 languages by subject-matter experts and taken 4,785 times by 2,911 unique users in 96 countries (Gartz et al., 2016).
Does Emotional Intelligence of Online Shoppers Affect Their Shopping Behavior? From a Cognitive-Affective-Conative Framework Perspective
Published in International Journal of Human–Computer Interaction, 2020
Moreover, our results suggest that online consumers are emotionally influenced in their e-commerce transactions. Thus, e-commerce business managers must develop an e-marketing plan using consumer’s emotional intelligence to offer their consumers a better shopping experience. For a successful business, especially e-commerce business managers need to utilize emotional intelligence to empower their e-commerce website. To do so, with the help of emerging ITs (e.g., Smart Mirrors, Augmented Reality, Artificial Intelligence, and so on), the traditional e-commerce websites employ emotion-based methods to improve the interaction with consumers and to enhance user experience in their website (Yi et al., 2015). For example, with the advent of IoT (Internet of Things) devices such as Smart Mirrors as a supporting feature of website through the internet, not only online consumers can try clothes or makeups virtually and order the products right away if they like but e-commerce websites also recommend clothe styles or makeups based on an emotional sensitivity of each consumer.3 In other words, e-business managers can develop marketing strategies focusing on the emotional sensitivity of their consumers, which allows tailoring products, services, and offers their customers a delicate choice (Yi et al., 2015). Simply put, utilizing the degree of consumers’ EI with an innovative technology, e-commerce companies can provide a comprehensive shopping experience to their consumers with a high level of customized services and advertisements, in turn, leads to consumer satisfaction and sale engagement.
Spectral analyses of trans- and cis-DOCO transients via comb spectroscopy

The absorption spectrum of each major species produced from the OD + CO reaction is shown in Figure 2. The large bandwidth of the high reflectivity mirrors spans a measurement range of 2380 to 2760 cm−1 (3.6 to 4.2 µm), which allows us to measure CO2, DO2, D2O, OD, cis- and trans-DOCO. The simulated OD and D2O line positions are obtained from Abrams et al. [38] and Toth et al. [39], respectively. The DO2 spectrum is simulated from measured rovibrational constants from Lubic et al. [40]. All spectra are simulated at T = 295 K, including that of the DOCO isomers, which, despite being produced with significant chemical activation from the OD + CO reaction, are rapidly thermalised to room temperature by high background concentrations of N2 and CO.
